Functions

func LogOptionsToQuery 

func LogOptionsToQuery(opts []LogOption) (string, string, int, error)

LogOptionsToQuery converts the given LogOptions to a URL sub-path and query string. Returns the URL sub-path and query string and the maximum number of commits to return from a Log query (or zero if none is provided, indicating no limit), or any error which occurred.

func ParseURL 

func ParseURL(u string) (string, string, string, error)

ParseURL breaks a gitiles URL into the repo URL, ref, and sub-path. Note that this is inherently error-prone due to the way that Gitiles URLs are structured: it is impossible to distinguish between the ref name and a path within the repo since both are separated by slashes with no other distinction. This function assumes that the ref name has a single component, eg. "refs/heads/main", or simply, "main".

Types

type Author struct {
	Name  string `json:"name"`

	Next string    `json:"next"`
}

Log represents a series of Commits in the git log.

type LogOption 

type LogOption interface {
	Key() string
	Value() string
	Path() string
